By rotating two sets of second handles, two sets of rotating blocks and two sets of threaded rods are connected, which drives two sets of movable plates to move, so that four sets of limit blocks descend vertically along the inner wall of two sets of slotted support frames. Finally, the two sets of movable plates descend vertically. With the connection of two sets of connecting plates, the two sets of second rubber wheels are in contact with the top of the wire rope, and the two sets of first rubber wheels are in contact with the bottom of the wire rope. The wire rope can be stably fixed during the testing process. The overall structure is simple, the clamping effect is good, and the practicality is strong.

[0035] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0036] like Figure 1-6As shown, an elevator wire rope flaw detection device includes a horizontal plate 1. Two clamping plates 2 are slidably installed at the bottom of the horizontal plate 1. Semi-circular through slots 4 are formed on the sides of the two clamping plates 2 that are close to each other. A flaw detection component 3 is fixed and passes through the clamping plates 2. A display and control component 5 is provided at the top of the horizontal plate 1. An installation groove 6 is formed at the bottom of the horizontal plate 1. Two sliding plates 7 are slidably installed in the installation groove 6. The sliding plates 7 are fixed to the corresponding clamping plates 2. A single bidirectional lead screw 8 is threaded through the two sliding plates 7. Two chambers 9 are formed on the horizontal plate 1. The two ends of the bidirectional lead screw 8 extend into the corresponding chambers 9 and are equipped with first gears 10. Rotating rods 11 are rotatably installed on both sides of the horizontal plate 1. One end extends into the corresponding chamber 9 and is equipped with a second gear 12. The second gear 12 meshes with the corresponding first gear 10. Through a simple limiting structure, it is easy to quickly limit and release steel wire ropes of different thicknesses, effectively maintaining the detection distance between the detection cable and the steel wire rope, and effectively improving the stability of steel wire rope flaw detection. The clamping plate 2 also includes a rectangular through hole 13, which passes through the two sides of the clamping plate 2 and communicates with the corresponding semi-circular through groove 4. The flaw detection component 3 is fixedly fitted with an installation sleeve 14, which slides through the rectangular through hole 13. A groove 15 is opened on the bottom inner wall of the rectangular through hole 13, and a slider 16 is slidably installed in the groove 15. Two locking rods 17 are fixedly installed on the top of the slider 16, and two slots 18 are opened at the bottom of the mounting sleeve 14. The top of the locking rods 17 are slidably installed in the corresponding slots 18. A lead screw 19 is threaded onto the clamping plate 2, and the lead screw 19 is rotatably installed at the bottom of the slider 16. This arrangement facilitates quick assembly and disassembly of the flaw detection assembly 3, making it easy to replace the flaw detection assembly 3 and effectively ensuring the detection effect on the wire rope. Two handles are fixedly installed on the top of the horizontal plate 1. Both flaw detection assemblies 3 are electrically connected to the display and control assembly 5 through wires. The handles facilitate the lifting of the detection device. Two limiting rods are fixedly installed in the mounting groove 6, and the limiting rods slide through the two sliding plates 7. By setting a limiting rod, the sliding plate 7 can be easily limited. A first through hole is provided between the mounting groove 6 and the chamber 9. The bidirectional lead screw 8 rotates through both first through holes. By setting the first through holes, the bidirectional lead screw 8 can be easily supported and limited. A second through hole is provided on one side of the inner wall of the chamber 9. The rotating rod 11 rotates through the second through hole. By setting the second through hole, the rotating rod 11 can be easily supported and limited. A threaded through hole is provided on the bottom inner wall of the groove 15. The lead screw 19 is threaded through the threaded through hole. By setting the threaded through hole, the lead screw 19 can easily drive the slider 16 to move. A circular groove is opened at the bottom of the slider 16. The top end of the lead screw 19 is rotatably installed in the circular groove. By setting the circular groove,This facilitates the rotatable connection between the lead screw 19 and the slider 16.

[0037] The working principle of this utility model is as follows: In use, the wire rope is first placed between two clamping plates 2. Then, the rotating rod 11 is rotated, which drives the second gear 12 to rotate. The second gear 12 drives the first gear 10 to rotate, and the first gear 10 drives the bidirectional lead screw 8 to rotate. The bidirectional lead screw 8 drives the two sliding plates 7-shaped mounting slots 6 to slide and move closer to each other, causing the two clamping plates 2 to slide and move closer to each other at the bottom of the horizontal plate 1 until the wire rope is limited within the two semi-circular through slots 4. Then, the two flaw detection components 3 are activated to perform flaw detection on the wire rope. This setup facilitates rapid limiting and release of wire ropes of different thicknesses, effectively maintaining the detection rate and... The detection distance between wire ropes effectively improves the stability of wire rope flaw detection. When the flaw detection component 3 needs to be replaced, first rotate the corresponding lead screw 19. The lead screw 19 drives the slider 16 to slide downward in the groove 15. At the same time, the slider 16 drives the locking rod 17 to slide out of the corresponding locking slot 18, so that the fixing of the mounting sleeve 14 is released. Then pull the flaw detection component 3, so that the mounting sleeve 14 is driven to slide out of the corresponding rectangular through hole 13. The flaw detection component 3 is removed and can then be replaced. This setting facilitates the quick installation and removal of the flaw detection component 3, thereby facilitating the replacement of the flaw detection component 3 and effectively ensuring the detection effect of the wire rope.
